I just found out that my rps 6-puck clutch blew up so I need a new clutch, and was wondering if I should try something different. I really have no idea what happened; I can only guess that it was somehow related to my previous accdient. Apparently all the rivots were ripped out and the whole thing was just in pieces. I'm not sure yet if my aluminum flywheel survived.

Anyway, should I stick with the same type of clutch or is there something better? I need something that's pretty streetable and can hold a lot of power. I didn't like how chattery the rps clutch was. Also, I was wondering if it was mainly my clutch or my light flywheel that was causing most of the chatter? Thanks.

Do you have a Unorthodox Crank Pulley?

That same shit happened to DT...

Noone shoudl run those fucking things without Harmonic Balancers...I've seen some Bearings outta Hondas from engines with crank pulleys on and they were all fucked up...

Anyways...Keep that Pressure plate and get a WOTM Disk or get a Tilton if your a Baller...or the new RPS Carbon-Carbon

The 6-puck clutches seem to chatter on both the factory and LW flywheels. If you don't mind the tranny rattle (as you have no doubt experienced with the LW flywheel) and aren't looking for a clutch to slip a lot upon hard launches, you might like the TRD Twin Plate. It has nice pedal feel and engages smoothly without chatter. I have a perfect, complete setup that has 12 easy miles on it. I pulled it out and replaced it with a 6-puck on a factory flywheel simply because I didn't like the rattling that the transmission does with ANY LW flywheel. Other than the rattling, the TRD is MILES ahead of the 6-puck in terms of civility.

SW's amazing [email protected] Supra has this RPS carbon-based clutch that should positive hold. To minimize drivetrain shock, pull the p. brake up, let out the clutch a bit till they rub, and rev the motor up. Do this only when both cars are staged to minimize clutch wear. You should be able to launch on boost as if you're brake torqueing an automatic car and run good times w/o nitrous.

I thought SW said he had the AZ disc.....

IME, when you begin to try to lightly slip the 6-puck clutches (as you suggest), they begin to chatter like crazy.

SW has the AZ clutch.

rps 6 puck chatter

That's what happened to my RPS 6 puck clutch. It never made any noise, but as soon as I made a couple passes at the track and slipped it, it started chattering once in a while. I thought I F-d something up. So how many passes at the track do these RPS 6pucks last? I only have about 4 passes on it now. I was thinking of making about 4 more before I go single.
thanks

For the record, it's NOT a AZ clutch. It's a WOTM disc. Brand new 6-puck design that holds. This is what I am using, and SW used for those awesome low 10 second passes. I highly recommend it. After break in it does not chatter.

Chris Bergemann is the "clutch killer" IMO, as he has had just every clutch out there and toasted each one. So far, his WOTM clutch is doing great, and he loves it. If you want to know if the WOTM is as durable as it is capable of holding HP, wait another month after Chris has been to the track a few more times.

As for a light weight flywheels, I haven't had one. But have heard enough of the rattle to stay away. I'd say your chatter was the flywheel, not the clutch itself. Did it make noise in neutral while stopped? If so, that's the flywheel.

Plus I don't think you can (or want to) use the WOTM disc with a lightweight flywheel.

My clutch/flywheel chatter a lot, loudest at neutral, and fairly loud through 1st gear and a little in 2nd. When the car is cold there is virtually no chatter but once it starts warming up it gets worse and worse. It's been like this since I first got it. I decided to go back to using a stock flywheel.. just ordered one from jaymarks. So you guys think I should stick with the rps pressure plate and a WOTM disc? I was also told the Ryan Woon disc was good. What do you think of ACT clutches? I heard one of those would be good too.

I got the RPS Stage 3 right now. Would it be possible to reuse the flywheel and pressure plate or should I go with a new one?

How much is the disk going for?

I was under the impression that the AZ clutch and the WOTM (located in AZ) clutch is the same thing. What other AZ clutch is there aside from the WOTM one?

Just for those who may be confused by the message below, chatter and rattle are two different things. Some clutches do neither, some do one without the other, and some do both.

Chatter is when the car shudders and jerks when the clutch is slipped a bit upon slow engagement, preventing the car from making a smooth startup from a dead stop. (Chatter may be especially bad when trying to start up in reverse gear.) It's caused by the disc alternately grabbing and slipping, grabbing and sipping.

The rattling noise comes from inside the transmission (not the flywheel) and results from NOT using the factory dual-mass flywheel that was designed to work in conjunction with the Supra transmission. The rattling can also result from the lack of damping provided by a worn out factory flywheel (worn out damping mechanism, not a worn out friction surface).

What I meant is that the guys at WOTM have stated that what people are callign the AZ clutch should be called the WOTM clutch. Same thing, just trying to get people into the habit of using the right name.

I am very happy with my RPS stage 3 and mueller lw flywheel, I have pulled multiple 1.5x 60' times with the best so far being a 1.50 and it seems to be holding up well so far. After killing 3 or 4 clutches I am happy to find something that works.

Angel, your civic is faster than your supra? haha. If you ever lose a race in your supra you should be like "let me go get my REAL car..." and come back in a civic and smoke their ass.. that would be sweet.
